PayPal covers all transaction fees. You’re donating to PayPal Giving Fund, a 501(c)(3) charity, subject to its terms. Donations can take up to 45 days to get to your chosen charity. It’s rare, but if PayPal can’t send your money to this charity, PayPal will ask you to recommend another. If PayPal can’t reach you, PayPal will send it to a similar charity and keep you updated. Your donation is typically tax-deductible in the US.
